Andy Ruiz Jr Shocks Boxing World By Stopping Anthony Joshua

It was a massive upset, one of the biggest in the history of heavyweight boxing.

Ruiz was a huge outsider going into the fight. In fact, he was only facing Joshua as the Englishman's originally slated opponent, Jarrell Miller, failed a drug test in the build-up.

The referee called a halt to the fight in the seventh round after Ruiz knocked Joshua down twice in the round and for the fourth time overall.
